Honestly, who gives a rip what the airplane is? I'd fly a Cessna 150 if the pay, schedules, and quality of life were right. The airplane is just a tool to deliver a big, fat paycheck to my back account for what I do in between days off.

It is that paycheck and those days off that allow me to go fly airplanes that are "cool". And, as it happens, there are plenty of schedules in that A300 "crappy domestic flying" that feature good quality of life for both commuters and non-commuters, and on widebody pay.
